| S.No. | Checkpoint | IS Requirement | Status |
|---|---|---|---|
| A. EXCAVATION ACCEPTANCE | |||
| A1 | Excavation approved and signed off — excavation inspection checklist (QC-SOL-CHK-001) completed and approved Acceptance: Excavation checklist filed with approvals; no outstanding NCRs from excavation phase | Mandatory | OK NC NA HOLD |
| A2 | Excavation bottom level correct — elevation ±25mm tolerance, no undulation >25mm across base measured with dumpy level Acceptance: Level survey certificate; RL recorded; deviation from design RL <25mm acceptable; level certificate signed | Mandatory | OK NC NA HOLD |
| A3 | Excavation dimensions verified — length, width match drawing ±50mm; all corners square (diagonal check within 50mm) Acceptance: Measured dimensions vs. drawing; diagonal check; tolerance verification documented | Mandatory | OK NC NA HOLD |
| A4 | Bearing stratum exposed — correct soil type, color, texture as per geotechnical report; no loose/disturbed material visible Acceptance: Geotechnical engineer site inspection; soil classification confirmed; bearing capacity per IS 6403 or report; approval memo filed | Mandatory | OK NC NA HOLD |
| A5 | Geotechnical engineer confirmation of bearing capacity — site visit conducted, foundation approval memo issued Acceptance: Geotechnical engineer approval document filed; bearing capacity confirmed; no reduction from design assumed | Mandatory | OK NC NA HOLD |
| A6 | No standing water in excavation — drained and pumped dry, ready for PCC placement Acceptance: Visual inspection; no pooling water; sump operational; base ready for construction | Mandatory | OK NC NA HOLD |
| B. PCC / LEVELING COURSE | |||
| B1 | PCC thickness min. 75mm (M10/M15 concrete) — leveling course between excavation base and rebar to avoid direct soil contact Acceptance: PCC thickness measured at multiple points; min. 75mm ±10mm; grade M10 or M15 specified; mix design filed | Mandatory | OK NC NA HOLD |
| B2 | PCC level within ±10mm — surface leveled after curing; no high spots or dips >10mm detected with straightedge Acceptance: Level checked with straightedge and level; variation recorded; rebar support bars clear of soft PCC | Mandatory | OK NC NA HOLD |
| B3 | PCC cured before rebar placement — min. 7 days curing or strength test ≥50% fck before loads applied Acceptance: Curing started immediately; wetted daily for 7 days; rebar placement begun only after 7-day cure or cube strength ≥50% fck | Mandatory | OK NC NA HOLD |
| B4 | PCC dimensions cover full footing + 150mm all sides minimum — overhang protects rebar and provides working margin Acceptance: PCC extends beyond footing perimeter by min. 150mm; edges level and clean; supports rebar off ground | Mandatory | OK NC NA HOLD |
| C. FORMWORK INSPECTION | |||
| C1 | Formwork dimensions per drawing — length, width, height, depth within ±5mm; no deviance from approved design Acceptance: Measured dimensions vs. drawing; tolerance ±5mm; adjustment made if needed before concreting | Mandatory | OK NC NA HOLD |
| C2 | Formwork depth (height) correct — footing thickness or raft thickness matches design ±10mm Acceptance: Measured at multiple points (min. 4 corners + center); uniform thickness verified | Mandatory | OK NC NA HOLD |
| C3 | Formwork clean and oiled — no debris, loose material, or algae; form oil applied to prevent concrete sticking Acceptance: Visual inspection; formwork interior swept clean; mold release agent applied uniformly | Mandatory | OK NC NA HOLD |
| C4 | Formwork tie wires and spacers secure — no loose ties; formwork rigid, no deflection >L/300 under self-weight + concrete pressure Acceptance: Ties tightened; no rattling or movement; no bulging detected; formwork supports adequate | Mandatory | OK NC NA HOLD |
| C5 | Pedestal/column starter location marked — location of column base marked on formwork for alignment; diagonals checked Acceptance: Pedestal location marked; alignment with structure above verified; center lines visible on formwork | Conditional | OK NC NA HOLD |
| C6 | Formwork support and bracing adequate — props/struts prevent movement during concreting; no settlement risk Acceptance: Support spacing verified; no weak points; props on solid ground; no bending or deflection visible | Mandatory | OK NC NA HOLD |
